The destruction of old ocean floor happens in 'subduction zones.'

旧海底的破坏发生在“俯冲带”。

And I love traveling to subduction zones all over the world.

我喜欢去世界各地的俯冲区。

We used to think that tsunamis only strike in areas where you have subduction zones.

我们过去认为海啸只会发生在有俯冲带的地区。

Ide is now doing a similar analysis on earthquakes that all happened in the same geologic setting, like subduction zones.

井出哲现在正在对所有同一地质环境下发生的地震进行相似性分析，比如说消减带。

Why don't we see it distributed throughout the entire subduction zone?

为什么我们没有看到它分布在整个俯冲带？

However, we didn't actually discover the Cascadia subduction zone until 1988.

然而，直到 1988 年，我们才真正发现卡斯卡迪亚俯冲带。

But subduction zone earthquakes actually give us a warning because the vibrations they cause travel at different speeds.

但俯冲带地震实际上给了我们一个警告，因为它们引起的振动以不同的速度传播。

On Earth, this recycling process usually happens at subduction zones, where the oceanic crust slides beneath the continental crust, warming as it goes down.

在地球上，这种循环过程通常发生在俯冲带，即海洋地壳滑落到大陆地壳之下，并在向下移动的过程中变暖。

Unlike other subduction zones and this is the crease right here, this plate would be diving below this plate here, which is just sitting here.

不像是其他俯冲带, 汇聚点就在这里, 这个板块将潜于位于这里的该板块之下。

A lot of subduction zone earthquakes are 200 miles deep, and there's a lot of padding between the shaking part and the earth surface where we live.

大多俯冲带的地震有200英里深, 而且地震和我们生活的地球表面之间有很多填充部分。
